BD680 Darlington Transistor, PNP, 80V 4A, TO126 Case
STMICROELECTRONICS BD680 PNP Darlington transistor, 80V 4A 40W, for industrial power management and amplification.
The BD680 is a robust PNP complementary power Darlington Transistor designed for demanding industrial and power management applications. Manufactured using Planar Base Island technology, it delivers reliable performance and high power density in a compact package.
This component features a monolithic Darlington configuration for high current gain and includes an integrated anti-parallel collector-emitter diode, simplifying circuit design and enhancing functionality. Its design prioritises stability with good hFE linearity and a high transition frequency (fT), making it suitable for amplification and switching tasks where signal integrity and speed are critical.
With a collector-emitter voltage (V(br)ceo) rating of 80V and a continuous DC collector current of 4A, the BD680 can handle significant power levels. Its power dissipation capability of 40W ensures reliable operation under load, supported by a maximum operating temperature of 150°C.
Housed in a through-hole mountable SOT-32 (TO126) case, it offers easy integration onto printed circuit boards for prototyping and production. The robust construction and proven technology make this transistor a dependable choice for engineers and technicians.
